Cochrane Library is a collection of databases that contain independent evidence to inform healthcare decision making. The Library contains over 5,000 systematic reviews (which summarize results of healthcare studies/controlled trials) and over 650,000 other data records, covering clinical trials, methods, technology and economic evaluations. Cochrane Library is a set of three databases, each with their own purpose:
Cochrane Database of Systematic Reviews
Cochrane Central Register of Controlled Trials (CENTRAL)
Cochrane Clinical Answers

According to its website, "the Campbell Collaboration is an international social science research network that produces high quality, open and policy-relevant evidence syntheses, plain language summaries and policy briefs." In other words, like the Cochrane Library, the Campbell Collaboration produces, supports, and shares systematic reviews related to social interventions.
